Broken cloud lifts to higher slopes
At dawn, variable patchy cloud possible at most heights, though highest tops above cloud at first. Cloud will rise to the higher slopes, remaining broken to expose tops at times; cloud banks possible more extensive on northern slopes.
Chance of cloud free Munros?
50%
Sunshine and air clarity?
A patchwork of cloud and sunshine, at times more cloudy on northern slopes. Very clear air on highest terrain, some haze lower down.
How Cold? (at 900m)

Planning Outlook
High pressure resides over the country through the week, maintaining quiet weather. In the mornings, varied low cloud and morning fog is likely while inversion conditions likely to remain over highest mountains for several days. A haze will linger on low slopes below the inversion. During midweek the inversion starts to weaken as pressure begins to fall gradually; cloud will be well-broken for many and begin to lift to higher terrain. Light winds overall, an easterly breeze likely for Wales. Uncertainty about the weather pattern development toward next weekend: some indication of strengthening winds bringing some rain, but may not reach all areas. Later October has hints of chillier northerly air, especially in Scotland.
